Technical Field
The utility model relates to the technical field of aluminum alloy gravity casting, in particular to a universal blank piston riser cutting mechanism.
Background
In the conventional gravity casting process of aluminum alloy, in order to obtain castings with qualified internal quality, a pouring system and a riser with proper structures are often required to be designed for assisting in the filling, forming and solidification of high-temperature molten aluminum, and the auxiliary pouring system and the feeding riser can become part of a product blank casting in the casting process and flow into the next working procedure along with the blank. Before the blank casting flows into the machining process, the pouring gate and riser parts on the blank casting are required to be cut off.
In the existing blank piston riser cutting process, a small-cylinder-diameter gasoline engine piston is placed on a special riser cutting clamp for cutting when the riser is cut, but a large-cylinder-diameter diesel engine piston cannot be placed on a gasoline engine tool for cutting due to large size, and can only be cut through manual clamping of a blank. Therefore, a universal blank piston riser cutting mechanism needs to be designed.
